Abstract (en)
[origin: WO03079100A1] An electro-absorption modulator comprises a waveguiding structure including a plurality of sections (201 - 205), each section having a different bandgap and at least one electrode for applying electrical bias to the section. An optical signal passing through the waveguiding structure may be modulated using the plurality of separately addressable sections, by applying a modulation signal to one or more of the sections, and electrically biasing one or more of the sections with a bias voltage, in such a manner as to achieve a predetermined level of any one or more of the parameters chirp, modulation depth and insertion loss.
